      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

SlimDX Warp Device using KeyedMutex

2 posts in this topic

I use Direct2D with DirectX11 via KeyedMutex. Everything works great if I am using a Hardware device. As soon as I default to Warp device I have a problem when I go to create a Texture2D object, I get the error message "Direct3D11Exception: E_OUTOFMEMORY: Ran out of memory"
These are the lines that are responsible:

[source lang="csharp"]SlimDX.Direct3D11.Texture2DDescription tds = SlimDX.Direct3D11.Texture2D.FromSwapChain(swapChain, 0).Description;
tds.BindFlags |= BindFlags.ShaderResource;
tds.SampleDescription = new SampleDescription(1, 0);
tds.OptionFlags |= ResourceOptionFlags.KeyedMutex;
textureD3D11 = new SlimDX.Direct3D11.Texture2D(device, tds);[/source]

Again, everything works great using a Hardware device, just not Warp. When I run it against PIX I see this:
<0x09033390> ID3D11Device:CreateTexture2D(0x0FD1E330, NULL, 0x0FD1E32C --> NULL)
That's using the Warp driver, but when I use Hardware that last NULL is not NULL, it's an actual pointer which points to a D3D11 Texture2D object. I've tried modifying the parameters of tds every way thinkable.

Any thoughts? I know I haven't included much code here but I was hoping someone would know what this was without having to post the whole DX routine. I will if requested.

I suppose it's possible that the Warp device is returning a new texture every time you call Texture2D.FromSwapChain, instead of reusing the previous one. In that case you'd have to Dispose() of the returned texture after you got its description. It'd be quite annoying if that were true.

Even if I switch to:
SlimDX.Direct3D11.Texture2DDescription tds = new Texture2DDescription();

I still get the out of memory error. I just thought I could save steps by using FromSwapChain by not having to supply parameters like height, width, format, etc...

I am using either DX 10.1 or DX10.0. Here is the entire debug output:

Using ID3D11Debug::ReportLiveDeviceObjects with D3D11_RLDO_DETAIL will help drill into object lifetimes. Objects with ExtRef=0 and IntRef=0 will be eventually destroyed through typical Immediate Context usage. However, if the application requires these objects to be destroyed sooner, ClearState followed by Flush on the Immediate Context will realize their destruction.

BTW, what is the best method to dispose of the swapchain texture then? I've been using this:
using (Texture2D texture = Texture2D.FromSwapChain<Texture2D>(swapChain, 0))

Will that just be creating a new one and disposing it? Edited by FrozT
